Title: Improvements in and relating to electromedical appliances
IPC: A61N1/32
Filed: 1955-01-24
Abstract: 766,504. Electromedical appliances. SPLADIS, SOC. POUR L'APPLICATION D'INVENTIONS SCIENTIFIQUES. Jan. 24, 1955 [Jan. 29, 1954; Aug. 24, 1954; Oct. 11, 1954], No. 2081/55. Class 81(2) An electromedical apparatus employs a condenser which is initially charged and is discharged in the form of pulses through the patient, suitable means being interposed to prevent the patient receiving the whole charge at once. In one simple form of apparatus, Fig. 1, the main condenser C is charged through a rectifier unit p, resistance r and high speed changeover controls L', L<SP>2</SP>, L<SP>3</SP>, L', driven by cam E, cause charges to be taken therefrom by subsidiary condensers C<SP>1</SP>, C<SP>2</SP> and passed to the patient P as individual pulses, the magnitude of which follow the state of charge of condenser C. These pulses are normally of large magnitude at the commencement of the operation but fall to a lower, steady level as the initial charge is withdrawn and the discharge rate becomes equal to the charging rate. The cam-operated contacts may be replaced by a system of rotating brushes mounted in a casing having adjustable fixed contacts. These are so connected (see Figs. 2 and 5, not shown), that charges are again taken from a main condenser and passed to the patient. Fig. 6 (not shown) shows an electronic arrangement in which pulses are derived from an oscillator stage and these are employed to charge a main condenser at a controlled rate so at to obtain the desired form of output.

Title: Manufacture of di-secondary alkyl poly-hydroxy phenols
IPC: C07C37/16
Filed: 1936-01-22
Abstract: Polyhydroxyphenols containing two nuclear-substituted secondary alkyl groups are prepared by heating the polyhydroxyphenol in the presence of fused zinc chloride with an aliphatic primary, secondary or tertiary alcohol for a sufficient length of time to p  cause two alkyl groups to enter the nucleus; water is then added, the mass heated until two layers are formed and the viscous top layer distilled in vacuo.  The products possess germicidal properties. Examples are given of the interaction of (1) pyrogallol with n-butyl, tert-butyl, tert-amyl, n-amyl, isoamyl, 1-methylbutyl, 2-methylbutyl, 1-ethylpropyl, n-hexyl, n-heptyl and n-octyl alcohols; (2) resorcinol with n-propyl, n-amyl, 1-methylbutyl, n-hexyl, n-heptyl and ethyl alcohols; and reference is made to the dihexyl derivatives of phloroglucinol and hydroquinone.  In general, molecular parts of the phenol and alcohol are employed and one-and-a-half molecular parts of zinc chloride, but other proportions may be used.  The products in each case contain two alkyl groups in the secondary form. Specifications 398,218, 415,715, 421,965, and 442,369 are referred to.

Title: Improvements in or relating to adjustable holding or locking devices
Inventor: COX ROBERT
IPC: E05C17/64
Filed: 1956-01-23
Abstract: 810,043. Locking slidable members. SLIDELOCK Ltd. Jan. 21, 1957 [Jan 23, 1956], No. 2211/56. Class 80 (3). [Also in Group XXV] A. modification of a locking device of the type described in Specifications 452,626, 569,723, 647,078, [both in Group XXV], 663,480, 663,481, and 673,756, comprising wedge members 5, 6 carried on one member 3 and urged by spring means 17, 18 into wedging engagement in a guideway in the other member 2, a strip 12 being secured on opposite sides of the guideway at spaced points and passing between the wedge members, consists in providing restricting means so that positive locking is obtained in one direction of movement and operating means for releasing the said restricting means as required. The restricting means are formed by the coupling plate 13 secured to the member 3 which houses the wedges 5, 6. Upstanding posts 20, 21 from the wedges 5, 6 respectively engage in slots 22, 23 of the plate 13, the post 20 having a clearance 22 on one side whilst the post 21 has a clearance on both sides when the device is in locking condition. A force on member 3 to the right will cause the plate 13 to act directly on post 20 to increase the locking action. A force to the left will cause plate 13 to move away from post 20 and allow the wedges to move in the guideway against only the wedging action of the springs. The operating means for putting the positive locking out of action comprises a cam member 25 on post 21 of wedge 6 which can be rotated into engagement with an abutment 27 on the plate 13 to move the plate away from its engagement with the post 20 of wedge 5. Thus a force on member 3 to the right will not cause the plate 13to contact post 20 so that the locking will only be derived from the wedging action if the springs in this direction as well. The cam 25 may be adapted to be actuated by a stop 31 on member 2 to release the acid operating means and apply the locking action at a certain relative position of the members 2 and 3. The stop may be movable to an inoperative position if desired.

Filed: 1941-02-25
Abstract: 543,138. Variable feed pumps. DODSON, E. Feb. 25, 1941, No. 2565. [Class 102 (i)] A variable feed fuel-injection or other pump for delivering accurately measured quantities of liquid, comprises a sealed chamber 2 containing a viscous liquid such as oil and communicating with inlet ports 14 in a barrel 4 having outlet ports 13 communicating with an intermediate chamber 3, a plunger 5 reciprocating in the barrel 4 to deliver the viscous liquid from the sealed chamber 2 to the intermediate chamber 3, a diaphragm 16 or the like constituting an elastic wall common to the intermediate chamber 3 and a pump chamber 17 containing the liquid to be pumped, and means for varying the relative positions of the inlet ports 14 and the plunger 5 so as to control the effective stroke of the plunger and therefore the feed of the pump. The viscous liquid is maintained under some pressure, and leakage losses compensated, by means of an elastic wall 11 loaded by a spring 12. The pressure in the pump chamber 17, which may be assisted by a spring 24, exceeds that exerted by the elastic wall 11 and holds the diaphragm 16 against a stop 25 at the end of the suction stroke of the plunger. The intermediate chamber 3 contains a supplementary piston 32 exposed at its outer end to the adjustable pressure of a spring 34 and also, by means of a passage 33, to the pressure in the sealed chamber 2. The head of the plunger 5 is formed with an oblique groove 26 constituting a release passage for enabling a portion of the viscous liquid to spill back through the inlet ports 14 on each delivery stroke of the plunger 5, and this spill back, and therefore the effective stroke of the plunger, is adjusted by rotating the plunger relative to the barrel. For this purpose the upper end of the plunger is formed with a pair of transversely projecting lugs 27 which engage in vertical slots 28 in a sleeve 29 formed with gear teeth 30 which engage a longitudinally adjustable rack 31.

Title: Production of cumene hydroperoxide
Inventor: BEWLEY THOMAS
IPC: C07C409/10
Filed: 1958-01-25
Abstract: The invention comprises a process for oxidising cumene in the liquid phase with molecular oxygen to give an oxidation product containing cumene hydroperoxide and unreacted cumene, separating, by distillation of the oxidation product, an overhead fraction containing materials boiling lower than cumene hydroperoxide and a concentrated cumene hydroperoxide fraction and recycling the overhead cumene fraction to the oxidation, wherein at least part of the overhead cumene fraction is fractionally distilled to remove materials boiling lower and/or materials boiling higher than cumene before being recycled to the oxidation.  Prior to the fractional distillation of the overhead cumene fraction, that fraction may be passed through and recovered from the process in which the concentrated cumene hydroperoxide fraction is decomposed into phenol and acetone.  The latter decomposition may take place in the presence of an acid catalyst such as sulphuric acid and in the presence or absence of added solvents such as acetone.
